Embodiment Construction

[0020] Since the RRU has the ability to transmit signals, in the embodiment of the present invention, the tested RRU is configured to generate a fixed pattern signal for testing the RRU, that is, to generate a test signal. In this way, the device for generating the RRU test signal composed of RRUs can serve as a signal source in the RRU test process, thereby eliminating the need for complex function signal source instruments in the prior art, and greatly saving test resources in the RRU test process.

[0021] The device for generating the RRU test signal in the embodiment of the present invention can be represented by an RRU test single board, see figure 1 , the device includes: a receiving unit 100, a configuration unit 200 and an RRU300, wherein,

[0022] The receiving unit 100 is configured to receive an output signal message in the current test mode.

[0023] The configuration unit 200 is configured to set the value of the downlink numerically controlled attenuator in the...

Abstract

Disclosed are a method and device for generating a test signal of a remote radio unit, so as to save test resources during an RRU test. The method comprises: receiving an output signal message in a current test mode; according to the amplitude in the output signal message, setting a value of a downlink digital attenuator in the remote radio unit (RRU); according to the saved correspondence between a reference frequency point and a compensation gain, acquiring a first compensation gain corresponding to a working frequency point in the output signal message, and according to the acquired first compensation gain, setting a power factor of a programming component in the RRU, so that the RRU, according to the value of the downlink digital attenuator and the power factor of the programming component, generates a test signal corresponding to the current test mode.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for generating a test signal of a radio remote unit. Background technique [0002] The remote radio unit (RemoteRadioUnit, RRU) is a new type of distributed network coverage mode. It places large-capacity macrocell base stations in an available central computer room. Pull it to the remote radio frequency unit and distribute it on the site determined by the network planning, thus saving a large number of equipment rooms required by conventional solutions; at the same time, by using a large-capacity macro base station to support a large number of remote optical fibers, the gap between capacity and coverage can be achieved conversion between. [0003] After the RRU is produced, it needs to be tested for uplink receiving data, and it can be put into use only after passing the test. The current test process includes: the signal source instrument dir...
